Applicati'onfiled October as, 1924. sale No. 745,454.

To all whom it may conccmz; Be it; known that. I, FLOYD .VVILLIAM LINTQN, a citizen of the United States, re-

siding at Ennis, inth'e county of Madison and State of Montana, have invented a new ing is a specification.

and useful Fish Guard, of which the follow- The present invention relates to a fish guard especially designed for use at the:

heads of irrigatingditches toexclude fish from t the. irrigating ditches for. obvious Another important object of the invention is to provide a device which will insure against logs, or other foreign matter from collecting at a point adjacent to the guard to render the guard inactive.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a plan view disclosing a guard constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the guard.

Figure 3 is a sectional view taken on line- 33 of Figure 2.

Figure 4 is a sectional view taken on line 44 of Figure 2.

Referring to the drawings in detail, the reference character 5 indicates the side walls of the guard proper, which walls may form continuations of the usual side walls of the irrigating ditch in which the guard is positioned.

Secured to the side walls 5 and extended upwardly therefrom are guiding members 6 which also act as supports for the vertically movable elongated bearing members 7 that are provided with openings to accommodate the water wheel shaft 8 on which jmembers 7.; p A gearlnghousing 1nd1catedi-at1-7 1s-ar-.

the water wheel mounted. .ThcSel mem bers 7 are provided with teeth 10 disposed along one edge thereof, which teeth mesh with the teeth ofthe pinions 11' mounted on the ends of the shaft 12, which shaft also carries a relatively large pinion 131meshing with theworm: 14 disposed at the upper'encl of the-rod 15,; the lower end of the rod 15' being. supplied with. an operating wheel 16 whereby the rod'l5, may be rotated to move the pinion 1-1 to raise or lowerthe bearing ranged adjacent to the shaft 8 in which gearing housing operates the pinion carried at one end of the shaft 8, the pinion meshing wit-h a relatively large pinion also mounted in the gear housing and carried at one end I of the shaft 19'.

This shaft 19 is square in cross section and moves in the tubular shaft 20 which is formed with a relatively squarebore to accommodate the shaft 19 so that rotary movement of the shaft 19 will produce a relative rotary movement of the tubular shaft 20 but at the same time permit of a sliding movement of the shaft 19 longitudinally of the tubular shaft 20 to compensate for vertical movement of the elongated bearing member 7 when it is desired to move the same longitudinally of its support to vary the depth of operation of the blades of the wheel 9. As illustrated by Figure l the shaft 20 is formed with a reduced portion 21- that carries a pinion not shown meshing with the relatively large pinion carried at one end of the shaft 2%, on'which the cylindrical guard to be hereinafter more fully described is mounted.

The cylindrical guard comprises end members 24 formed with inwardly extended flanges 25 around which the wire mesh material 26 is positioned and secured. Formed in the guarding member is a recessed portion 27 which defines a pocket throughout the length of the cylindrical guard, the depth of the pocket being sufficient to allow sticks, or other foreign matter to enter and be passed through the-irrigating ditch in which the device is positioned.

Arranged adjacent to the cylindrical guard is a pivoted plate 28 which wipes the surface of the cylindrical guard in a manner to prevent material from choking the pocket or passing to a position between the bottom wall 29 of the irrigating ditch and the guard, to retard movement of the rotary guard. Stub shafts 30 are formed at the ends of the plate 28 and are positioned in suitable openings formed in the sidewalls of the guard proper, so that the plate may be moved with comparatively lit tle' exertion on the part of the operator.

Angularly disposed "bracing bars 31 have connection with the uprights 32 and 33, at the lower ends of the bars 31, while the upper ends of the bars 31 are connected with the guiding members 6 to hold the -gfuldlng members 1n the r upright positions.

From the foregoing it will be seen that as water passes through the guarding memher, the water contacting with the blades of the water wheel 9 causes the same to reing associated with the shaft 21.

Owing to the fact that the cylindrical guarding member is constantly rotating, it will be seen that a certain noise in the Water adjacent to the guard will be produced, to the end that the fish which may be caught in the ditch will not move sufficiently close to the guard to become caught and carried beyond the guard.

I claim In a fish guard, a rotary cylinder formed of wire mesh material, the periphery of the cylinder having an elongated depression extending from one end thereof to the other end, said depression providing a pocket, said pocket includinga substantially radial Wall and curved wall, and said radial wall adapted to pick up articles to carry them upwardly. r

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

FLOYD WILLIAM LINTON.
